What can bad power steering cause?
The symptoms of a bad steering pump include:
- Your Car Makes a Whining Noise Any Time You Turn the Wheel.
- Your Car’s Steering Wheel Is Slow to Respond.
- Your Car’s Steering Wheel Is Stiff.
- Your Car Makes Squealing Noises When You Turn the Key in the Ignition.
- Your Car Makes Groaning Noises.
What does a bad power steering pump mean?
Groaning noises are a sign of a lack of fluid in the power steering system and can eventually damage the whole system, including the steering rack and lines. They will get increasingly worse as your power steering pump continues to fail and could lead to a complete power steering system replacement.
What happens when a power steering rack fails?
Like the power steering rack, the steering pump runs at a high pressure from 400-900 PSI. When the rack is failing or has failed, the steering pump is still running with little to no oil. The rotor bushing is now wearing faster than it would.
What causes a power steering system to leak?
Contamination of the fluid can happen when the pumps fail, hoses deteriorate or any outside moisture enters the fluid. Such problems all result in contamination of the fluid, likely causing small openings to plug up the steering system, an increase in friction, or even interference with the fluid’s hydraulic characteristics.
What causes a power steering pump to turn gray?
A whining sound along with fluid that has turned to a nasty gray color definitely indicates a problem with your pump. If a bearing in the pump is going out, a dark gray color could result from fine metal shavings caused by the bad bearing mixing with the power steering fluid.

Why does my steering rack make a grinding noise?
This is different from the groaning/whining noise that is commonly heard when the power steering pump is low on fluid. It occurs the same way, when turning corners at low speeds. Grinding is an indication that low or contaminated fluid has damaged the pinion gear and steering rack.
Where does the power come from in a steering rack?
The “power” part of the steering comes in the form of pressurized fluid in steering rack passages that assist the driver in turning the wheels. The fluid also keeps everything cool and prevents damage in the metal-on-metal gear contact.
What should the fluid level be on a power steering rack?
If the vehicle calls for automatic transmission fluid (ATF) then it should be full, red, and clean. If the vehicle calls for normal power steering fluid then it will be light brown or clear. If the fluid level is low, add more until it reaches the full line, and go for a test drive.
